Our Top 10 Email Subject Lines: What Gets Emails Opened and Why
An email that never gets opened cannot work. Subject line quality determines whether your email gets read or deleted — and most businesses invest almost no thought in this single most important element of their email marketing.
What Makes a Subject Line Work
The best subject lines create curiosity, specificity, or urgency. They avoid the generic formats that have trained inbox habits to ignore — 'Monthly Newsletter', 'Company Update', 'July News'. Instead, they make a specific promise, ask a direct question, or use an unusual phrase that makes the recipient pause before deciding to delete.
Proven Subject Line Patterns
Curiosity gaps work — 'The mistake most businesses make with proposals.' Specificity works — 'Why 47% of your emails never get read.' Direct questions work — 'Are you making this mistake?' Names in subject lines work in B2B. Short subject lines often outperform long ones. Emojis can significantly boost open rates. The common thread across all of these is standing out in a crowded inbox.
Test Before You Trust
No subject line tip can tell you with certainty what your specific audience will respond to. The only reliable method is testing — send two versions to segments of your list, measure open rates, and adopt the winner. Subject line testing is free, fast, and one of the highest-return marketing activities available to any business with an email list.
